How to send data with OSC to LiveLinkPose

I want to send OSC data to UE4, like LiveLinkFace.

And I want the LiveLinkPose node to receive the data.

However, looking for documentation doesn’t seem to describe in detail how to send and recieve the OSC.

I know how to send a simple OSC, but I can’t understand what format the LiveLinkPose plugin is receiving data from.

Does anyone know more about LiveLink?
